A new metal-organic framework, {[Cd(DPA)(OBA)]center dot(H2O)}(n) (1, DPA = 4,4'-dipyridylamine, H(2)OBA = 4,4'-oxybisbenzoic acid), has been synthesized and characterized by elemental analysis, IR and single-crystal X-ray diffraction. Single-crystal X-ray analysis shows that it is a 3-D framework. Complex 1 crystallizes in monoclinic, space group C2/c with a = 21.699(7), b = 12.192(4), c = 17.566(5) angstrom, beta = 105.254(5)degrees, V = 4483.43 angstrom(3), Z = 8, D-c = 1.653 g/cm(3), = 1.021 mm(-1), F(000) = 2240, the final R = 0.0307, wR = 0.0867 (I > 2 sigma(I)). Complex 1 exhibits a rare three-dimensional highly 8-connected LOMFOI topology with a point symbol of {4(24)center dot 6(4)}. Thermogravimetric analysis shows that the decomposition temperature of the host framework of the complex is above 400 degrees C.
